Critical Vulnerability in NestJS Devtools: Localhost RCE via Sandbox Escape
A flawed sandbox in @nestjs/devtools-integration lets attackers run code on your machine via CSRF, leading to full Remote Code Execution (RCE).
Control flow for ES7 async/await with async.js (v2) signatures
async-aa provide javascript async/await equivalent signatures of the excellent async workflow library.
Module are exported in standard commonJS module format and written in pure ES7 strict format. (no transpilation required nor used). Use browserify if you need async-aa modules in a browser environnement.
async-aa is not a wrapper on async, but rather leverages the full potential of native async/await & promises contract. Code tend to be small & very efficient (far more simplier than using callbacks), just give async-aa/queue.js a look
Nothing special here
// = eachLimit concurrency = 1
// = eachLimit concurrency = arr.length
Nothing special here neither
// = eachOfLimit concurrency = 1
// = eachOfLimit concurrency = dict.length
const eachLimit = require('async-aa/eachLimit');
(async function *() {
var stuffs = [1,2,3, 5, 7]
await eachLimit(stuffs, 2, function*(id){
await dootherStuffs(id);
});
})();
Call a function in javascript next tick (using setImmediate API, or timeout 0 pollyfill)
Return a QueueObject you can push task into.
Wait for thunk to process task (wait for worker, if needed)
const queue = require('async-aa/queue');
const fetch = require('node-fetch');
var q = queue(fetch, 1); //let's be nice
co(function *() {
await q.push("http://example.com/stuff.json");
});
co(function *() {
await q.push("http://example.com/otherstuff.json"); //will wait for stuff to be retrieved
});
Throttle any function that return a promise, sugar syntax helper for async-aa/queue
const throttle = require('async-aa/throttle');
var fetch = require('node-fetch');
fetch = throttle(fetch, 1); //make fetch behave nicely
co(function *() {
await fetch("http://example.com/stuff.json");
});
co(function *() {
await fetch("http://example.com/otherstuff.json"); //will wait for stuff.json to be retrieved
});
async-aa is tested against async test suite.
